Arc vs straight through putting strokes: Your complete guide

For many golfers, putting can be an afterthought. A part of their game that’s rarely given enough attention, compared to the likes of driving and teeing off. Yet putting is just as technical – described as a ‘game within the game’ – that you’ll need to master in order to be a well-rounded golfer.

If you want to be ruthless on the green and capitalise on your successful approaches, you’ll need to devote time to putting. And that includes experimenting with which putting style works best for you. Here, we’ll explain what the difference is between straight-through putting and arc putting, and we’ll give you tips on how you can try each to see which style gives you the best results.

What is a straight-through putting stroke?

With a straight-through stroke – also often called straight back, straight through (SBST) – you’re attempting to keep the putter moving straight along the target line throughout the putting stroke.

If you’re standing over your ball with your putter in hand, imagine a straight line running through the ball. Your backswing will travel along that line, as will your follow-through. Your club should strike the ball at a 90-degree angle (right angle) with the face flat. Imagine a pendulum-like motion, swinging smoothly back and forth along a straight line.

The theory with straight-through putting is that, as the putter travels straight and the face stays square, the ball should start on line, allowing you to more easily line up your putts. It’s a very controlled style of putting that should ideally give consistent results.

However, executing straight-through strokes perfectly is more complex than it sounds, as most golfers have some degree of arc (deviation from a straight line) in their putts. This is caused by their body mechanics, swing motion, and even the geometry of the putter.

What is an arc putting stroke?

Rather than a straight line, an arc putting stroke follows a gentle curve during the motion of the putter head.

If you’re standing over your ball, imagine a straight line running through it again. However, on your backswing, your putter will move in an arc that travels slightly inside this target line. Your swing returns to the line at impact, and then moves back inside the line on your follow-through. Your club face should open slightly on the backswing, strike the ball flat, then close slightly on the follow-through.

This curving movement isn’t arbitrary. It’s a result of natural biomechanics. Because the putter shaft is angled and your shoulders rotate around your spine, the club naturally swings on a tilted plane, creating an arc.

Although it may seem more complicated than straight-through putting, the idea with arc putting is that it follows a more natural motion and is more achievable than following a straight line, especially on longer putts. 

How to perform a straight-through putting stroke

To practice straight-through putting, you should:
 
1. Form a square setup, with:

• Your eyes directly over the ball
• Your shoulders parallel to the target line
• The ball positioned centrally

2. Keep the putter on line:

• Visualise a straight target line running through the ball
• Picture the putter moving straight back along this target line
• Use alignment aids or a putting mirror if you need to

3. Minimise face rotation:

• Keep the putter face square throughout your swing
• Focus on a smooth “pendulum” motion

4. Control the movement with your shoulders:

• As you swing, rock with your shoulders evenly
• Keep your wrists stable

5. Maintain a straight follow-through:

• Extend the putter down the target line after impact
• Avoid pulling across the ball

How to perform an arc putting stroke

To practice arc putting, you should:

1. Set up carefully:

• Position your ball slightly forward of centre
• Stand with your eyes slightly inside the ball
• Let your arms hang naturally

2. Focus on your shoulder rotation:

• Think of your shoulders rocking, not your hands
• Avoid any extraneous wrist movement

3. Allow yourself to follow the natural arc of your swing:

• Let the putter move slightly inside on the takeaway
• Don’t try to ‘keep it straight’. Trust the motion

4. Square the face at impact

• The goal of your swing is to make sure the putter’s face is squared at the point of impact
• Let the putter release naturally

5. Match your backswing and your follow-through

• Your backswing and follow-through should be symmetrical on either side of your ball
• Maintain a consistent rhythm and avoid deceleration through the ball

Which putting style is right for you: arc vs straight-through?

The simple answer is the one that works best for you.

Arc putting tends to be a more natural approach for many golfers, which results in a more fluid swing. However, some golfers will get better results by perfecting a straight-through putting style, benefitting from the control it offers.

Some golfers even find they can vary their putting approach, using an arc stroke for longer shots and straight-through putting for shorter shots (as it can be harder to achieve a straight line on longer swings). However, varying like this can be difficult, and isn’t usually recommended for beginner players.

The reality is that most golfers have some degree of arc during their swing, even if they consider themselves straight-through putters. Often, the real difference between the two styles is a subtle one in how much arc is present.

It’s a good idea to film your stroke from above, if you can, or to use putting aids such as alignment sticks around your putter to find out whether you naturally tend more towards arc or straight-through putting. Once you know which, you can focus on perfecting your putting with the style that suits you best.

Matching putters to your putting style

Once you have an idea of which putting style you prefer, you can also find the right putter to suit it, further helping to improve your game:

• Straight-through stroke: Typically suits face-balanced putters, as these are designed to stay square during the stroke.
• Arc stroke: Typically suits toe-hang putters, as these are designed to rotate naturally, which suits the arc motion.

However, as with your stroke style, choosing the right putter for you is also a question of experimentation to find what works best for your game.

Finding your putting style

No single putting style is arbitrarily better than the other. One of either arc or straight-through putting may suit your game better, or you may find you can use either style for different putts.   

The key is to stop forcing a technique that fights your natural motion. Instead, understand your stroke, match your equipment, and build a repeatable process so you can approach your putts with the confidence that comes from knowing you can control the line of your ball.

Arc vs straight-through putting FAQs

Which putting stroke is more common?

Whilst many golfers begin with straight-through putting, arc putting is usually more common as it aligns with how the body naturally moves during the stroke and typically leads to more fluid swings.

Which is easier, arc or straight-through putting?

As arc strokes follow a more natural movement of the body, many golfers find arc putting easier. However, this is a personal preference, and plenty of golfers prefer straight-through putting. Which style is easier will depend on you.

Is straight back and straight through (SBST) putting a myth?

Not entirely, but a perfectly straight stroke is extremely difficult to achieve. Most golfers will always have some degree of arc due to the angle of the putter and shoulder rotation. In reality, the difference between SBST and arc putting is more of a spectrum than two polar opposite approaches. 

Do professionals use arc or straight strokes?

Most professional golfers use a slight arc, although the amount varies. Very few players use a completely straight stroke, amateur or professional.

Why was anchored putting banned?

Anchored putting, where the putter is fixed against the body (such as the chest or chin), was banned by the R&A and USGA in 2016.

The governing bodies determined that anchoring reduced the challenge of the stroke by removing the need to control the club freely, which they felt was a fundamental skill in golf. The ban specifically targets the act of anchoring, not the use of long putters themselves.

Does AimPoint putting actually work?

Yes, AimPoint can be highly effective when used correctly.

AimPoint is a green-reading system that uses feel and slope percentages to determine break. Many tour professionals rely on it because it provides a structured, repeatable way to read greens.

However, its effectiveness depends on your ability to use it effectively.  For amateur golfers, AimPoint can be extremely helpful, but only if you commit to learning the system properly.
